How AI Works Infographic

Artificial Intelligence, or AI for short, is like a computer playing dress-up as a human brain. Like how we learn from experience, AI systems learn from collected data, identify patterns, and make decisions. 

Using machine learning, AI systems learn to think like humans or attempt to at least. They take in information, process it, and then do something useful. Think of it like your friend who always wins at Trivia Night because they soak up facts like a sponge. 

According to Forbes, 84% of businesses believe investing in AI will increase competitive advantages. So, understanding AI is like knowing the secret handshake at an exclusive club!


Lately, Generative AI (the creative type) caught everyone’s imagination. It can create articles, music, images, and videos quickly. It powers chatbots (ChatGPT), image generators (DALL-E), and even the content editor I’m using for this blog post (Jasper AI).

Essential AI Terms: An A-Z Guide

AI (Artificial Intelligence)

AI is like your clever friend who can learn things on their own. It’s a branch of computer science where machines mimic human intelligence – thinking, understanding, solving problems, and improving over time. 

AI Accelerators

AI Accelerators are special hardware that turbocharges AI processing. They give computers a boost, helping them handle AI tasks faster and more efficiently. These specially designed hardware pieces make AI programs run smoothly, saving time and energy!

AI Ethics

AI Ethics is like a rulebook for making sure our digital pals (AI systems) play fair, stay open (transparency), take responsibility (accountability), respect our secrets (privacy), and remain secure (security). 

It helps ensure that AI is developed in a beneficial and fair way for everyone and considers society’s values and cultural norms.

AI Models

AI models are like the “brains” of artificial general intelligence. They are made by feeding a machine learning algorithm with lots of data to train on. The algorithm then uses this data to learn patterns and make smart decisions, just like our brains do when we learn something new.

AI Side Hustles

AI side hustles are money-making opportunities that use AI to perform tasks with little or no human input other than typing in a few ‘prompts’. 

Examples include using large language models like ChatGPT or Google Bard to write an e-book, automatically respond to customer questions, or make new art pieces for a design project. 

These easy-to-use platforms offer an exciting opportunity to earn money online and learn how to use AI.

Algorithm: The Backbone of AI

An algorithm is like a recipe or computer system. The machine follows a step-by-step guide to solve a problem or complete a task. It can predict, classify, or group data, making it the brain behind the idea.

Application Programming Interface (API)

APIs are a set of instructions that help two software programs interact. Think of an API as a waiter in a restaurant. You, the customer, ask for something (you make a call). The kitchen (the system) uses the waiter (the API) to understand your request and deliver what you asked for. 

It’s a go-between that helps two parts chat and get things done.


An autonomous machine, in simple terms, is a self-governor. It’s a machine that gets stuff done without any human help. Think of a self-driving car cruising on its own. That’s autonomy in action!

Big Data: A Big Deal in AI

Big Data is like the vast and deep ocean of the digital world. It refers to massive datasets that are too complex for traditional methods. We can collect, store, and study it to spot patterns or trends. 

As AI advances, the demand for Big Data grows. AI heavily relies on training data to learn and improve. The more data it has, the better it performs. That’s where Big Data comes in, providing a wealth of information for machine learning.


This is about how sentences can vary in length or complexity in a text. When humans write, they often have bursts of different lengths, like a long sentence followed by a short one. But AI-generated text can lack this variation, with sentences that are consistently similar in length or complexity. Burstiness measures how natural or human-like the text seems in terms of its variation.

Chatbot: The AI Conversationalist

A chatbot is an incredible tool that mimics human conversation using text or voice commands. It’s widely used in customer service and content delivery, using natural language processing to understand and answer your questions. 

AI chatbots are revolutionizing technology by simulating human conversation and providing accurate responses. It’s fantastic, and now you can get support even when the humans have long gone to bed 🛏️

Cognitive Computing: Thinking Machines

Cognitive Computing, in a nutshell, is AI! It’s just another less scary name to describe the same idea. Cognitive Computing mimics how humans think – Learning, reasoning, and problem-solving. 

It’s found a lot of use cases in industries like healthcare, finance, and customer service, making tasks easier and more efficient. 

Computer Vision: Machine Perception

Computer vision, in simple terms, is about teaching machines to ‘see.’ It’s a tech field where AI-based systems interpret and understand the visual world. This involves devices identifying images or videos, similar to how humans use their eyesight and brain to understand sights.


In AI speak, a corpus is like a mega-library for AI machines full of training data. It’s a massive dataset of written or even spoken language information that trains AI machines, like learning a language from books and conversations. That’s how AI goes from babble to chatter.

Data Mining: Unearthing Insights

Data mining is like AI’s super sleuth, sifting through truckloads of data to unearth hidden patterns, trends, and correlations. It’s all about cleaning up data, spotting the ‘odd one out’, making predictions, and grouping similar data. 

  • Data Cleaning: Tidying up the data and removing unnecessary clutter.

  • Pattern Tracking: Finding repeating trends like the beat of a song.

  • Classification: Sorting data into groups, like apples and oranges.

  • Association: Uncovering links between variables, like salt and pepper.

  • Outlier Detection: Spoting data points that don’t fit the pattern.

  • Clustering: Grouping similar data.

  • Regression: Predicting trends, like seasonal weather.

  • Prediction: Making educated guesses, like a data fortune-teller.

Data Science: The Art and Science of Data

Data science uses math, statistics, and computer science to find meaningful insights from big data. It’s like being a detective, using data clues to make decisions and discover new opportunities. 

Data science is closely connected to big data, which means analyzing large datasets to find patterns and trends for business decisions.

Datasets: Feeding the AI

Datasets are like food for AI. They’re collections of related information, sort of like your favorite playlist, sorted out neatly with tags. Your AI needs them as training data for machine-learning models. They’re vital to making your AI smarter.

Deep Learning: AI’s Deep Dive into Data

Deep Learning is a part of AI that mimics the human brain by learning how humans process and use information to make decisions. 

It learns from raw, unstructured data without being told what to do. It’s like teaching a toddler to recognize dogs from cats. The ‘toddler’ (or AI) will figure it out with enough examples!

Generative AI: The Creative Aspect

Generative AI is like a virtual content creator. It generates new text, images, or even code by learning from existing data. It’s a game-changer in creative and technical fields, bringing AI-driven innovation and speeding up content creation. 

Using neural networks, generative AI identifies patterns in large data sets to produce fresh content.

Generative Adversarial Networks: AI’s Competitive Edge

Imagine GANs as two artists in a contest – a forger (the generator) and an art critic (the discriminator). The forger’s job is to create paintings so good that the critic believes they’re genuine. Meanwhile, the critic is trained to tell real from forged. 

They train together, and over time, both get better, creating an artful game of AI cat-and-mouse.

GPT: AI’s Language Learner

GPT, developed by OpenAI, is like a brainy linguist who has mastered natural language processing to generate human-like sentences by drawing from its big data source. 

It learns from tons of historical data, grasps language patterns, and then spins out sentences that sound just like we humans wrote them. GPT has become the most talked about and recognizable AI model.

Hyperparameters: Fine-tuning the AI

Think of hyperparameters like the knobs on a soundboard. Just like how you tune knobs to get the perfect sound, in AI, you tweak hyperparameters to get the best learning results for your model.

Hyperparameters affect how an AI model learns. But remember, they’re set manually, not discovered by the model. 

IBM Watson: Venture into Applied AI

IBM Watson is a powerful AI service from IBM designed to understand, learn from, and naturally interact with humans. It can integrate with apps, analyze big data, and provide insights while learning over time to make smarter decisions. 

Image Recognition: AI’s Vision 

Image Recognition is how AI systems identify stuff in pictures or videos. Like humans use their eyes and brains, AI uses deep Learning and neural networks to spot patterns in each tiny pixel. 

It excels at spotting faces, reading license plates, or helping robots and self-driving cars see what’s happening around them.

Large Language Models: AI’s Language Powerhouse

Large Language Models (LLMs) are AI models trained on massive datasets to grasp language understanding and generate text that sounds like a human wrote it. 

LLMs power AI writing software, such as Jasper AI and Writesonic, making content writing more accessible and faster for hobbyists and pro writers. 

Think of it as having your own AI-powered writing buddy!

Limited Memory: AI’s Storage Considerations

In simple terms, limited memory in AI is like a short-term brain for machines. It briefly holds data from recent happenings, using it to make smarter decisions. 

It’s like how we remember what we studied for an exam for the day, use it, and then it’s gone.

Machine Learning Model

Machine learning involves building systems that accept new data, learn from it, and then adjust based on the latest info without human supervision. 

It’s making computers smart enough to improve their performance without humans manually programming them.

Natural Language Generation (NLG): AI’s Linguistic Capability

NLG is the way AI translates its language (data) into a language humans can understand (text or speech). 

In essence, it transforms structured data into simple human language. You see NLG in action when your weather app tells you about the upcoming rainstorm or when Siri gives you directions.

Natural Language Processing (NLP): Understanding Human Language

Natural Language Processing (NLP) is a process that helps computers understand and generate human-like language.

 It takes complex structured data and turns it into human text or speech. It makes tasks like email filtering, language translation, and search suggestions easier. 

NLP has two parts: Natural Language Understanding (NLU) and Natural Language Generation (NLG). Natural Language Understanding interprets what we say, while NLG generates human-like language. Together, they make it possible to interact naturally with machines. 

So, when your email filters spam or your smart assistant sets a reminder, that’s NLP in action!

Neural Networks: Mimicking the Human Brain

A Neural Network is a cool type of machine learning model that works like our brain. A neural network uses ‘deep learning’ to process tons of data and learn tasks, just like our brain learns from sensory data. From recognizing faces to dominating board games, neural networks make technology smarter! 🧠

No-code Development: Simplifying AI

No-code AI development uses visual, code-free platforms to build and deploy AI models. It’s a game-changer in the AI world! 

Its drag-and-drop features are user-friendly, allowing anyone, even without coding expertise, to create AI models. This means quicker, easier AI integration, lowering costs, and spreading the power of AI far and wide. 

Overfitting: The Pitfall in AI Learning

Overfitting is like studying for a test with an answer key – you know the solutions to that set of problems, but can you handle new ones? 

In AI, overfitting happens when a model learns the training data too well, failing to generalize and perform effectively on unseen data in the machine learning training environment.

PaLM 2: Googles LLM

PaLM 2 is Google’s new Large Language Model (LLM) with enhanced multilingual and reasoning capabilities. This Transformer-based model is more intelligent, efficient, and faster than its predecessor. 

Parameters and Classification: AI’s Decision Making

In simple terms, parameters are like the AI’s recipe ingredients, the variables. Through the learning process, these variables get adjusted, improving the accuracy and relevancy of results. 

On the other hand, classification is like the AI’s method of sorting these ingredients, breaking down raw data into groups based on their similarities or differences. 

Pattern Recognition: Making Sense of Data

Pattern recognition is when AI gets a sense of déjà vu. It uses algorithms to sift through data, spotting repeated patterns. They then label the similarities to categorize this data. 

Think of it like sorting socks:

  • The AI is the sorter.

  • The data is an enormous pile of socks.

  • The patterns are the matching pairs.


This is a measure of how well a probability model predicts a sample. In simpler terms, it’s a way of quantifying how “surprised” an AI model is by the text it sees. Lower perplexity means the text is more predictable for the model. In AI-generated text, perplexity can be used to gauge how closely the generated text matches the patterns the model has learned. Generally, AI-generated text might have lower perplexity compared to human-written text because it tends to stick to more predictable patterns of language.

Predictive Analytics: Foreseeing with AI

Predictive analytics is like your own crystal ball powered by AI. Using machine learning and data mining, it takes historical data, analyses it, and predicts what will happen in a given time. 

Prescriptive Analytics: AI’s Suggestion Box

Prescriptive analytics uses data, AI, and algorithms to suggest optimal courses of action, helping organizations make smart, strategic decisions. 

It involves analyzing past and present data to make predictions about future outcomes and prescribe the best next steps.

Prompt Engineering: Guiding AI 

Prompt engineering is like being the director of an AI show. By popping in the right words, questions, and phrases (prompts), you guide AI models to create the desired outputs. 

It’s about giving the machine enough information to accurately pick out the correct data to craft your best response. 

Think of it as the secret sauce to make your AI more efficient and effective without the techy jargon.

Quantum Computing: AI’s Quantum Leap

Quantum computing, put, is a super-charged type of machine learning computing.

It uses quantum bits or ‘qubits,’ which, unlike classic bits that are either a 0 or 1, can be both at the same time thanks to a funky quantum property called superposition. 

This allows quantum computers to process massive amounts of data way faster than traditional computers. 

Reinforcement Learning: Reward-based AI Learning

Reinforcement learning is like teaching a dog new tricks. It’s a type of machine learning model where an algorithm, or “dog”, interacts with its environment (tries tricks). 

If the trick is good (reaches the goal), the dog gets a treat (reward). If not, there is no treat (penalty). 

Our AI’ dog’ learns the best tricks (solutions) through this process.

Structured Data: Organized Information for AI

Structured data is like a neatly organized closet. Information is organized in a standard format, often tabular, with clear rows and columns. 

Easy for computers to digest, it’s a goldmine for AI due to its structured, quantitative nature. 

Think of phone numbers, dates, or product SKUs – that’s structured data.

Supervised Learning: Guided AI Learning

Supervised Learning is machine learning where algorithims get trained using labeled datasets. 

It’s like a guide showing the machine the connections between input data and the correct output. 

The machine then learns these patterns and makes accurate predictions when new, similar data is fed to it.

Text Generation: AI’s Writing Skill

Text generation is like AI’s way of turning data into words based on queries. Trained on big data, models like GPT or BERT analyze natural language processing patterns, style, and context. 

With math, stats, and intelligent algorithms, they create human-like text, like the tools that bloggers and content writers now use for AI generated articles and images. They’re excellent at discovering answers from big data pools, from blog articles to sales messages.

The Turing Test: AI’s Intelligence Quotient

The Turing Test, named after Alan Turing, assesses AI by having a human judge a conversation between a person and a machine. If the judge can’t tell them apart, the machine passes, showing human-like intelligence. 

This test measures the machine’s language and behavior abilities.

Alan Turing

Transfer Learning: Sharing Knowledge in AI

Transfer learning in AI improves machine learning accuracy. It’s when a model learns from one task and applies that knowledge to a similar one. 

Let’s say your model excels at analyzing product reviews. You switch it to tweets for a bit. When you go back to studying product reviews, it uses its new knowledge of tweets, making it even better.

Unstructured Data: The Messy Part of Data

Unstructured data is the unorganized and messy info that doesn’t fit neatly into databases. Think of videos, emails, social media posts, or audio files. It’s a big chunk of the data universe, but it takes a lot of work to search and analyze. AI can help us make sense of it.

Unsupervised Learning: AI’s Independent Learning 

Unsupervised Learning is a self-guided form of machine learning that adapts from unlabelled data, free from direct supervision or human feedback. It’s like a student exploring a new topic, spotting patterns, and gaining insights on its own.

Voice Recognition: AI’s Listening Skill

Voice recognition, or speech recognition, is when a machine listens, understands, and responds to human speech. It’s the magic behind Siri and Alexa, turning your spoken words into actions, whether sending a text or ordering a pizza.
